Product Applications/Installation
All portions of duct designated to receive QuietR
®
Rotary Duct Liner shall be completely covered with duct
liner, adhered to the sheet metal with 90% coverage of adhesive complying with ASTM C 916. Transverse
joints shall be neatly butted and there shall be no interruptions or gaps. All transverse joints shall be
edge-coated. Metal nosing on leading edges must be used where duct liner is preceded by unlined metal,
and on all upstream edges when velocity exceeds 4,000 fpm (20.3 m/s). The black mat faced surface of the
duct liner shall face the airstream. NOTE: 150’ rolls are rolled with the black mat to the outside.
QuietR

Rotary Duct Liner shall also be secured with mechanical fasteners, either impact-driven or
weld-secured, which shall compress the duct liner suf ciently to hold it fi rmly in place. For fastener spacing,
see Figure 1.
Duct Liner shall be cut to assure overlapped and compressed longitudinal corner joints. For details, refer to
NAIMA Publication AH124, Fibrous Glass Duct Liner Standard.
Minor damage and small tears may be repaired by coating with adhesive – ASTM C916.
After installation, and prior to occupancy, blow out duct system to remove any cutting scraps or foreign
material remaining in the duct.
Multiple Layer Installation Instructions
Installing two layers of material to meet a speci c liner thickness is not recommended. If the specifi cation
forces the use of multiple layers, the following steps must be taken:
1. Adhere bottom layer of duct liner to duct in normal manner.
2. Adhere top layer to bottom layer of liner using a minimum of 90% adhesive coverage.
3. Treat all leading edges with metal nosings to prevent separation of the two layers.
4. Use mechanical fasteners of the proper length for double layer.
